Thanks.  I found out a little more, if I pass

  -Wl,--accept-unknown-input-arch

on the gcc commandline, it's happy and falls through to complaining 
about the lack of cross libc which is correct for me.  So it seems it 
has the idea that the libgcc.a file has "unknown arch" and that makes 
the problem.

Unfortunately there's no simple way of working around that by glueing 
that option into the defaults I could find.

I studied your 4.1 libgcc.a contents as well, there isn't any thumb 
related routine in that old version but nothing in that guy reports "no 
machine".

Maybe it's a genuine issue with 4.5.0 libgcc build somehow, I'll try 
your suggestion.
